Abstract
An engine control apparatus comprises a plurality of sensors for detecting the operation state of an engine, means for calculating, on the basis of signals produced from the sensors, a correction amount which corrects a predetermined controllable quantity, means for calculating a learned correction amount by averaging values of the correction amount by a reference occurrence frequency, means for calculating, under a predetermined condition, the learned correction amount by averaging values of the correction amount by an occurrence frequency which is smaller than the reference occurrence frequency, and means for correcting the controllable quantity in accordance with the correction amount and the learned correction amount.
